sound glitching

The program keeps glitching everytime you write, change or play a note, it playing mode, it keeps glitching to and skiping times in the count of the metronome.

In adittion, I have to say that I use the program to write guitar Sheets, so, the bending articulation function doesn´t make any sound in the playing mode.

I had a video attached to this so you can take a look of what I am telling you.

Thank you in advance for your help
